How Much Does It Cost To Renovate A House In The UK? A 2025 Guide

This is our guide to home remodeling expenses. When thinking about making changes to your house or purchasing a house to renovate, there are several factors to consider. Estimating the renovation’s expected cost is a crucial choice. We outline the typical cost to renovate a house as well as general factors to consider when purchasing a home to renovate.

How to locate a home remodeling opportunity that you may purchase

You need to look through the available properties if you are planning for a home renovation project. Consider the type of project you wish to do. Consider a bungalow or a tiny house on a large plot if you’re seeking a way to expand your home’s footprint and add a large addition.

As an alternative, consider older three- or four-bedroom semi-detached or terraced homes if you’re searching for something with solid structure but need a lot of work. After you have an idea of what you might desire, use the property portals to explore your alternatives. The other element guiding your search will undoubtedly be the amount you can afford to pay to purchase the house and renovate it.

Don’t get overly excited yourself when you find a possible project while looking for properties for renovation. Take a step back and look at the wider picture before you even begin to imagine what you could do to the location.

What about the things that are beyond your control? Will they limit the possibilities of the property? Consider:

Location: The house cannot be picked up and moved. Does it have convenient local schools, good transportation connections, and other amenities? Furthermore, keep in mind the ancient saying that it is preferable to purchase the worst property on the best street rather than the finest house on the worst street.

Neighborhood: Examine other properties in the area. Have they undergone any significant renovations, loft conversions, or additions? You’ll get a sense of how friendly the local planning officers are from this.

Limits: Any limits should be specified in the property details. You might not be able to make some changes if it is leasehold, in a conservation area, or covered by a restrictive covenant.

The price of an extension

One of the primary prices of home improvement that you are probably thinking about is the cost of an extension.

What is the price of converting a loft?

Another approach to upgrade and increase the value of your house is to convert your loft. Loft conversions in homes start at about £20,000, but depending on what you need done, the price might go up significantly. It costs about £45,000 to convert a loft with dormer windows to add a bedroom and an ensuite bathroom.

The cost of installing a new bathroom in a house

New bathrooms typically cost £6,000. However, the degree of luxury you want and the amount of new plumbing needed might cause this price to increase significantly.

What is the price of a new kitchen?

Your home’s worth can increase by thousands of dollars with a stunning new kitchen. However, it can also cost thousands. 10% of us spend more than £50,000 on a kitchen renovation project, even though the typical cost of a new kitchen renovation is between £10,000 and £20,000. 

How much would converting a garage cost?

Since garage conversions typically cost £6,000, they’re a fairly affordable method to expand living space and raise a home’s worth.

What is the price of rewiring?

It’s crucial to get the electrical system of an older home inspected. Fabric-coated flex leads, outdated light switches, and antiquated fuse boxes are all indicators that your system is outdated.

Numerous factors, such as where you reside, the size of your home, whether it is occupied, and how old your home is, will affect the precise cost of rewiring your house. Obtaining at least three quotations is what we would advise.

Don’t choose the least expensive quote after you get them. Examine prior work that has been done and consult with other customers. 

The cost of replacing windows and doors

Make sure you have authorization before beginning any plans to install double glazing. You will require listed-building approval if your property is listed. Additionally, you may need planning approval to make changes to your windows or doors if your house is located in a conservation area.

After receiving approval, the cost of an average-sized uPVC window, including installation, should be between £400 and £600.

What is the price of modern central heating?

The average three-bedroom home will cost about £4,000 to add central heating if it doesn’t already have it.

Your budget will be less affected by a residence that requires a new boiler but currently has central heating. British Gas estimates that replacing an old combi boiler with a new one will cost about £2,700. 

What should I budget for a new roof?

Replacing the roof might be one of the most expensive home improvement projects. Depending on the size of your property and the degree of the work required, you should budget between £4,500 and £12,000 if your survey indicates that you need a new roof. This will depend on things like if the rafters need to be replaced and the kind of tiles you desire.

Think about if anything else needs to be replaced at the same time if you are spending money on structure for a new roof. What condition is your guttering in? 

Conclusion:

In the UK, home remodeling can be a big but exciting job. Knowing what you’re getting into financially is crucial, regardless of whether you’re remodeling the space, adding an addition, or installing a new kitchen. Every project is unique, and expenses may rise up rapidly, particularly when those small unexpected surprises occur, which they usually do!

The best course of action is to carefully prepare, budget a little more, and always seek professional guidance before making any decisions. Take a broad view, analyze the long term, and keep in mind that a well-planned restoration can transform an outdated, damaged property into your ideal home and increase its value significantly.
